Rolling multi-face overturning device and square matrix rolling multi-face overturning device

Abstract

Provided is a rolling multi-face overturning device. The rolling multi-face overturning device comprises an outer frame, wherein an upper reel and a lower reel are installed in the outer frame in a relative rotation mode, a poster is arranged between the upper reel and the lower reel in a winding mode, a first transmission wheel is connected with the upper reel in a transmission mode, and a second transmission wheel is connected with the lower reel in a transmission mode. The rolling multi-face overturning device further comprises a motor, wherein the motor is provided with a driving shaft, a driving wheel is connected with the driving shaft in a transmission mode, the driving wheel is connected with the first transmission wheel or the second transmission wheel in a transmission mode, a winding-unwinding tensioning shaft is further installed in the outer frame in a relative rotation mode, a winding-unwinding tensioning wheel is connected with the winding-unwinding tensioning shaft in a transmission mode, the winding-unwinding tensioning wheel is connected with the second transmission wheel or the first transmission wheel in a transmission mode, a pulley block is arranged between the driving shaft and the winding-unwinding tensioning shaft, the pulley block comprises a fixed pulley, a lifting differential movable pulley and a strip, the fixed pulley is installed in the outer frame in a relative rotation mode, and is arranged between the driving shaft and the winding-unwinding tensioning shaft, the two ends of the strip are fixedly connected with the driving shaft and the winding-unwinding tensioning shaft respectively, and the lifting differential movable pulley is connected with a gravity adjusting pendant.

Description

technical field [0001] The invention relates to a multi-sided flip, in particular to a rolling multi-sided flip and a phalanx rolling multi-sided flip. Background technique [0002] At present, the products used for advertising include picture-changing light boxes, which have the following disadvantages: [0003] 1. Large-scale advertisements cannot be realized: the maximum size is below 18 square meters; [0004] 2. There are 2 motors for the upper and lower reels, which drive the upper and lower reels respectively. The circuit is complicated and the cost is high; [0005] 3. If a lot of ordinary picture-changing light boxes are combined, due to structural limitations, the distance between the pictures of the two light boxes is very large, which seriously affects the effect of the picture; [0006] 4. In order to prevent the picture from being deformed by the wind, the light box has a glass cover to protect it, but it is impossible to completely protect it with glass for ...

AI Technical Summary

Problems solved by technology

[0003] 1. Large-scale advertisements cannot be realized: the maximum size is below 18 square meters;

[0004] 2. There are 2 motors for the upper and lower reels, which drive the upper and lower reels respectively. The circuit is complicated and the cost is high;

[0005] 3. If a lot of ordinary picture-changing light boxes are combined, due to structural limitations, the distance between the pictures of the two light boxes is very large, which seriously affects the effect of the picture;

[0006] 4. In order to prevent the picture from being deformed by the wind, the light box has a glass cover to protect it, but it is impossible to completely protect it with glass for large outdoor advertisements

[0008] 1. Generally, the picture ring structure is adopted (that is, the upper end of the first picture is connected with the lower end of the last picture), which is prone to picture deviation;

[0009] 2. The picture will be deformed after being blown by the wind, so it cannot be used outdoors;

[0010] In addition, I once invented a large-scale scrolling advertising machine, but I used two wire ropes to drive the upper and lower reels. Because the logical direction of the two wire ropes plus the direction of the picture is very complicated, and because the winding direction of the wire rope is changing all the time, the operation Difficult, high failure rate
